PAPER PRESS PROCESS WITH HIGH HYDROLIC PRESSURE

Abstract:

The present invention provides compositions comprising cellulose fibers and cellulose ester fibers and wet laid articles made from the compositions, as well as wet laid processes to produce these compositions. More specifically, the present invention provided compositions comprising cellulose fibers and cellulose acetate fibers and wet laid articles made from these compositions as well as wet laid processes to produce these compositions. The present invention also relates to developing a composition, process, wet laid product, or articles exhibiting any one of many desired benefits. Specifically, a wet laid process comprising a process that allows the quantity of water removed from a web passed through press rolls is increased relative to a web made from a 100% cellulose comparative composition or any composition without cellulose ester staple fibers co-refined with cellulose at the same press loading
